San Diego  A driver was arrested on Interstate 5 Monday after Border Patrol agents found 14 pounds of cocaine hidden in his car’s trunk, authorities said Tuesday.

The agents stopped the Mitsubishi Lancer north of the Border Patrol checkpoint near San Clemente about 1 p.m. and a drug-sniffing dog detected drugs. Agents then found six bundles of cocaine concealed in a box in the trunk, officials said.

The drugs, valued at $145,000, were seized. The 20-year-old driver, a U.S. citizen and San Diego resident, was arrested.

Earlier that morning, agents also seized 185 pounds of marijuana in a separate smuggling attempt at the Interstate 15 checkpoint in Temecula. The 59 packages were hidden in a compartment under the floor.

The 26-year-old driver and 50-year-old passenger, both Mexican nationals, were arrested.
